patch 8.0.1625: test_quotestar is flaky when run in GTK GUI commit https://github.com/vim/vim/commit/29dfa5af3c14406573d08609d2e95add4d6b45fb Author: Bram Moolenaar <Bram@vim.org> Date: Tue Mar 20 21:24:45 2018 +0100 patch 8.0.1625: test_quotestar is flaky when run in GTK GUI Problem: Test_quotestar is flaky when run in GTK GUI. Solution: Do not call lose_selection when invoked from selection_clear_event().

" Settings for test script execution
" Always use "sh", don't use the value of "$SHELL".
set shell=sh

" Only when the +eval feature is present. 
if 1
  " While some tests overwrite $HOME to prevent them from polluting user files,
  " we need to remember the original value so that we can tell external systems
  " where to ask about their own user settings.
  let g:tester_HOME = $HOME
endif
